1 Starting up conditions

Starting up of OVF20 system only should be performed by authorisizied personal!

Caution!

Opening of of the package has only to be done for reasons of repairingand may only happen if you have checked by measurement that the mainswitch is off and the value of DC-link voltage is 0 Vdc. Only then you canbegin with maintenance.

The controller cabinet has to be mounted in a distance of 50 mm between wall and theheatsink of the drive.

The mechanical works of hoistway and cabine as well as machine room and hoistwayinstallation have to be finished to ensure inspection run.

The electrical connections have to be installed completely and checked.

Attention !

Do not bridge over safety devices and door contacts!

2 First Inspection Run (without Encoder)

2.1 Checking of voltages

1) Switch the unit to ERO-operation2) Switch on the main switch3) Check the power supplies according to the diagram in TRF1.4) After switching on, the DR (Drive Ready)-signal on the MCB II must be active, (Checking

by SVT), it indicates the readiness of the inverter (at MS300 and MCS310 OP-relay willenergize).

5) It must be checked if the following inputs of the MCB II have the correct voltage of24VDC

P3.2 (24V - output)P4.7 (/1LS - signal)P4.8 (/2LS - signal)P3.1 (DBD - signal) in each case to P3.3 (HL2)

2.2 Input Signals Check on the MCB II using the SVT

Connect Service Toool to MCB II.With <Module> <1> <2> <GO ON> check input signal DBD.

2.3 Set of Default Values

By setting of standard values signigficant parameters are adjusted for starting up.Activation is due to by:<Module> <3> <6> <ENTER>

Remark:For runs in INS- or ERO- mode also the correct controller type (CONTR TYPE) and correctcontract speed (CON SPE) have to be adjusted by <M> <3> <1> <GO ON>.An inspection run without encoder is further possible if the number of impulses (ENCODERPULSES) is set to Zero.

2.4 Check of Direction

After setting of standard parameters you should check the run direction with the ERO-Box.For INS- or ERO- operation the MCB II needs the input signals UIB or DIB (<M> <1> <2><GO ON>).The main contactors SW1and SW2 have to be activated. The activation is done by theMCB II in connection with UP- or DOWN- signals if the safety chain is closed. In the sametime the DBD-input will be inactive.

With the Service Tool the status of the drive can be controlled (<M> <1> <1> <GO ON>).

By pushing of UIB- or DIB-buttons the motor will start.If the run direction is not the same as the wanted direction, then two conductors of themotor cable have to be exchanged.You must check if the drive reduces speed to creep speed when the cabine reaches theswitch 1LS or 2LS (only by MCS220).If the car does not move the error can be detected by means of status display.If Shut Down (SHT DWN) is displayed the reason can be found out by means of Errorlogging (ErrLog) (<M> <2> <2> <1> <GO ON>).By off and on switching of the main switch in decided cases of Shut Down the blocking canbe cancelled.

3 Adjustment of magnets

Magnets with a length of 170 to 250 mm can be used. At shorter landings you have toconsider that the distance between door zones must be at least 180 mm. Otherwise thedoor zones can not be separareted with normal speed.

In controllers with learn run, the stopping distance is generated by the MCB II software.

Note:Following problem can occure if a correction run starts in down direction near by 1LS (or2LS for up. Then the drive decelerates in 1LS to creep speed and creeps the whole dis-tance to the door zone. If now the distance between 2LV and 1LV & 2LV is too long, relayLVC drops off and disables relay LV2 to pull in. The door bypass circuit is opened. With itthe door zone was not detected and the car runs to the limit switch (7LS).The solution is, the magnets 1LV and 2LV have to be as narrow so far as the failure doesnot occure. In the terminals that distance haven‘ t to be longer than 35mm.

5 Learn run

At units with integrated MCS 220 - or MCS 220 M - Controllers with Learn run the Learn runhas to performed. Normal runs are not possible without previous Learn run. A repeatition ofthe Learn run is necessary if a door zone magnet was removed or if the parameterCON SPE was changed. Before starting the Learn run, the parameters CON SPE, CONTRTYPE, TOP FLOOR und FLOORS in 1LS (<M> <3> <1> <GO ON>) have to be adjusted.Check the 1LS distance before starting the learn run!

6 Final adjustment of the drive

Following parameters have to adjust fundamental for each unit.- Contract parameter

(Drive parameter will adjusted automatically by setting of the parameter CON SPE fornormal runs.)

- Vane parameter(Have to be adjusted at normal run.)

- Drive parameter(Additional parameter for short runs or manual adjusted speed profiles.)

6.1 Contract parameters

1. NOM FREQU = 500 for 50 Hz= 600 for 60 Hz

(nominal frequency of the motor)2. CON SPE = Contract speed at nominal frequency, given by mechanic

(gear, traction sheave and so on)

Attention !

For parameter CON SPE a calculation is necessary !

* Nominal frequency of the motor (50 Hz or 60 Hz).

3. N SYN MOTOR [rpm] = Synchronuos motor speed by 50 Hz (or 60 Hz) (e.g. 1000, 1500).

4. ENCODER PULSES = Number of speed encoder pulses per trace. The number of pulse can vary between 118 - 129 according to use with GO 177 CK1, especially with 11 VTR machines.

5. ENCODER TRACES = Number of traces of the Speed encoder6. 2LV (1 = Yes / 0 = No) = 1 ⇒ 1LV/2LV-door zone

= 0 ⇒ LV-door zone (only 1 LV-signal)7. DDP (s) = Run time controlling8. CONTR TYPE = 0 ⇒ MS 300, MCS 310

= 1 ⇒ MCS 220 (M) without coded interface= 2 ⇒ MCS 220 (M) with coded interface V1-V4, DS1-DS2= 4 ⇒ MCS 220 (M) with coded interface and with learn run

9. ACC PRECTR = Frequency precontrol to compensate the torque of inertia. After 10 normal runs, enter the value of SVT-display (right, above). If the value impossible round down!

10. SLIP LOAD = Slip, during full load in up direction. Run with empty car in downdirection or with full load in up direction and enter the value of SVT-display (right, above) Is the value impossible round up !

6.2 Drive parameter <M> <3> <2> <GO ON> (Speed profile)

The drive parameter will be adjusted automatically by setting the CON SPE, change only ifit is necessary e.g. to reduce the normal run speed or the enable short landing or releveling.

1.) INS SPE (0.01 m/s) Inspection run2.) NOM SPE (0.01 m/s) Speed at Normal run3.) SHR SPE * (0.01 m/s) Short distance - speed4.) REL SPE (0.01 m/s) Releveling speed5.) CRE SPE (0.01 m/s) creep speed6.) ACC (0.01 m/s2) acceleration rate7.) DEC (0.01 m/s2) deceleration rate8.) JERK (0.01 m/s3) Acceleration changing

* At controllers with learn run, the short distance speed is adjusted by the software.

6.3 Vane parameters <M> <3> <3> <GO ON> (Normal run withencoder)

For the following normal runs the input signals NOR (NORMAL) UIB, DIB and U or D and Tfor MCS 310 and MS 300 or V1-V4 for OTIS 2000 will be used.

Before adjusting the vane paramters (hoistway signals), a trip through hoistway signalsshould be done (inspection run).The switching of IPU/IPD, (SLU, SLD), LV, (1LV, 2LV) 1LS and 2LS switches should bewatched with the Service Tool <M> <1> <2> <GO ON>.

After this test the vane-parameters should be adjusted (hoistway variable).

The next step is to search a „adjusted floor“ in teh middle of the hoistway.

6.3.1 LV DLY UP and LV DLY DOWN (Adjustment of floor level)

Check the floor level in down- and up-direction.Stopping failures will be removed by chanching the parameters LV DLY UP [mm] (Stoppingfailure direction up) and LV DLY DOWN [mm] (Stopping failure direction down).

If the car is stopping to early (before level), this value has to be higher (+ the stoppingfailure in mm).If the car stopping to late (after level), this valu has to be lower (- stopping failure in mm).If the magnets are adjusted in the same manner at each floor, the car should stop correctlyin each landing, otherwise the magnets should be adjusted accordingly.

6.3.2 IPU/ IPD DLY (Adjustment of creep time)only at controllers without Learn run

The creep time (CREEP TIME) should be 300 ms - 500 ms.Adjustment is done by changing the parameters IPU DLY and IPD DLY.If the creep time is too long, these values should be increased.The minimum value for IPU-DLY and IPD-DLY depends on the contract speed of the car.The creep time of the last run is displayed in SVT display (right, above) unit in 10 ms steps.If the deceleration is started by limit switches in the terminal landings, „1LS/2LS“ isdisplayed in the SVT display.

Attention !

Each IPU/IPD-signal must be active for longer than 150 ms(else „MLS: /T <> IP „would be registered) !

Speed min. value0,5 m/sec 50 mm

0,63 m/sec 63 mm0,8 m/sec 80 mm1,0 m/sec 100 mm

6.3.3 1LS, 2LS (Adjustment of deceleration limit switch)

1LS DLY and 2LS DLY have to be adjusted in the way that in the top and bottom landingthe deceleration will be activated by the IPU- or IPD-signal.Is the deceleration started by the limit switches in the terminal landings, a „>„ is displayed inthe SVT display.Increase the value for 1LS DLY or 2LS DLY, until the „>„ character, after a new run, doesn’toccure.The value should not be too large for a sure deceleration by correction run.1LS- and 2LS DLY have to be increase, till the failure „MLS:1LS INI DEC“ in the bottomlanding and „MLS:2LS INI DEC“ in the top landing, while stopping, is removed.Only at correction runs this failure is allowed and can be read in the event logging(ErrLOG = 2 <M> <2> <2> <1> <GO ON>).Conditions in the event logging does nor generate automatically a shut down of the unit.The explanation of the events are described in the chapter „Service Tool User Guide“.The unit should be switched off and on (main switch) to reset the event logging counter.If requested you can find the saved events in the menu „Saved“ (<M> <2> <2> <2>).At following test runs no failure should be registered in the event logging.Exception: DRV:SPEED MSMT“ and „SYS: Calc Time“.

Attention !

Note adjusted parameter and lie down them in the controller.Store the parameter setup with <M> <3> <7> in the EEPROM.Do not choose the Default-values, otherwise the adjusted contract-specificparameters will be lost.It is helpful to store adjusted parameter in the controller cabinet, because with thatthe drive can be readjusted rapidly after change of EPROM or MCB II and setting ofdefault values.

7.2 Elevators with load weighing (at contollers with learn run)

If the elevator is equipped with load weighing, then the load switches can be used to opti-mize the start jerk.The load switches are connected to P4.5 and P4.6 (only at CONTR TYPE = 4, otherwiseSLU/SLD inputs) and should be adjusted to 25% i.e. 65% of full load.The adjustment can be done with empty car in inspection mode :• Run car into top position.• Set parameter PREMAG PER to 100.• Start car in down direction. Adjust PRET FREQ so that the car does not move during

premagnetisation. Adjust NEG PRET as low as possible.• Run car into bottom position.• Start car in up direction. Adjust NEG PRET so that the car does not move during pre-

magnetisation. Adjust NEG PRET as low as possible.• Set PREMAG PER to the old value.

• Set PRET SLOPE to 2 upto 4 (at 13 VTR to 2).

If the start jerk is worse in up direction than in down direction (empty car), then increaseparameter Ustart. Too much increasement could implicate vibrations at creep speed.

The adjustment is finished and the start jerk one person up is reduced significantly.
